	bfd/
	* elf32-arm.c (a8_erratum_fix): Add st_type field to record the
	destination mode of the a8 stub.
	(elf32_arm_link_hash_table): Add top_id field.
	(elf32_arm_link_hash_table_create): Initialize top_id.
	(arm_type_of_stub): Update prototype, st_type can now be updated
	by this function. Actual destination address in case of PLT is
	computed here, to help factorizing code.
	(elf32_arm_stub_name): Update prototype, use stub_type additional
	parameter to build stub name.
	(elf32_arm_get_stub_entry): Update prototype, use stub_type
	additional parameter to build stub entry.
	(arm_build_one_stub): Use bfd_put_16/bfd_put_32 instead of
	put_thumb_insn/put_arm_insn as BE8 encoding is now handled later.
	Call elf32_arm_final_link_relocate to process all in-stub
	relocations.
	(elf32_arm_setup_section_lists): Update top_id.
	(cortex_a8_erratum_scan): Record stub destination mode.
	(elf32_arm_size_stubs): Update call to arm_type_of_stub according
	to new prototype.
	(elf32_arm_final_link_relocate): Enable processing of in-stub
	REL32 relocations. Rely on arm_type_of_stub to detect if a stub is
	needed, enabling code factorization.
	(elf32_arm_final_link): Process stub sections.
	(elf32_arm_output_map_sym): Add entry to code/data map.

	ld/testsuite/

	test.

		README for LD

This is the GNU linker.  It is distributed with other "binary
utilities" which should be in ../binutils.  See ../binutils/README for
more general notes, including where to send bug reports.

There are many features of the linker:

* The linker uses a Binary File Descriptor library (../bfd)
  that it uses to read and write object files.  This helps
  insulate the linker itself from the format of object files.

* The linker supports a number of different object file
  formats.  It can even handle multiple formats at once:
  Read two input formats and write a third.

* The linker can be configured for cross-linking.

* The linker supports a control language.

* There is a user manual (ld.texinfo), as well as the
  beginnings of an internals manual (ldint.texinfo).

Installation
============

See ../binutils/README.

If you want to make a cross-linker, you may want to specify
a different search path of -lfoo libraries than the default.
You can do this by setting the LIB_PATH variable in ./Makefile
or using the --with-lib-path configure switch.

To build just the linker, make the target all-ld from the top level
directory (one directory above this one).

Porting to a new target
=======================

See the ldint.texinfo manual.

Reporting bugs etc
===========================

See ../binutils/README.

Known problems
==============

The Solaris linker normally exports all dynamic symbols from an
executable.  The GNU linker does not do this by default.  This is
because the GNU linker tries to present the same interface for all
similar targets (in this case, all native ELF targets).  This does not
matter for normal programs, but it can make a difference for programs
which try to dlopen an executable, such as PERL or Tcl.  You can make
the GNU linker export all dynamic symbols with the -E or
--export-dynamic command line option.

HP/UX 9.01 has a shell bug that causes the linker scripts to be
generated incorrectly.  The symptom of this appears to be "fatal error
- scanner input buffer overflow" error messages.  There are various
workarounds to this:
  * Build and install bash, and build with "make SHELL=bash".
  * Update to a version of HP/UX with a working shell (e.g., 9.05).
  * Replace "(. ${srcdir}/scripttempl/${SCRIPT_NAME}.sc)" in
    genscripts.sh with "sh ${srcdir}..." (no parens) and make sure the
    emulparams script used exports any shell variables it sets.
